The plants are not especially remark-able, since they are heterozygous for red, andorange is dominant to the light yellow of theprimrose. These crossed together, however,should give one in sixteen homozygous red on aprimrose ground, which ought to be a very finevariety. Horticulturists will recognise that theSunflower is following the lines of variation al-ready familiar to us in the genera Helenium andGaillardia; but owing to the tall growth andlarge size of Sunflower heads, the effect from agardening standpoint is very different.

THE GHENT 123.—socratea forgetiana, exhibited in the class for new plants. (See page 294.) appears in the recently-published catalogue ofMessrs. Sutton & Sons. The explanation of theap-pearance of the bicolor form appears to be this :the wild Sunflowers, many of them, carry a factorfor marking, which can be seen on very carefulinspection, indicated by a slight difference inthe intensity of the orange colour on the basaland apical parts of the rays. When the redfactor is introduced, the marking comes outstrongly, and the rays are deep red basally,with thu» apsx orange. Some writers have ridi-culed the idea of a marking factor where nomarking is seen, or, at least, is obvious, butthere can be no doubt that such a thing exists,both in plants and animals. In addition to thevariations described, many flowers show red onthe middle of the ray, the base and apex beingyellow. The e
